What's the easiest way to correct an over full crankcase? The previous owner put in too much and it's coming out in the airbox. It's about 1/8" past the top line. That's checking by placing the dipstick in the hole and NOT screwing it in.

vacuum pump/brake bleeder is nice if you have one, but if you had one, you probably would have already thought of that.

BTW, you probably know this, but the oil level is read off of the dipstick after it's been screwed all the way in- so your oil probably about 5/8" or 3/4" too full.
